I know that there's a wet mane Celestia that's a recolor of that Rarity base (like has already been done for every pony ever) but Celestia and Rarity don't look very similar, and I wanted to do things right. Besides, this way was more fun!

Looks like the account is gone already, but as this is not the first time there's been a pinkamenadianepie ripping off art, I can't help but wonder if they haven't just moved up to a different account with much the same username.
